To provide a water bottom shape measurement device advantageous to simplify a configuration while suppressing cost.SOLUTION: A three-dimensional shape measurement part 14E hung from an unmanned flight body 14 through a support member 20 is positioned underwater, a three-dimensional shape of a water bottom 22 is measured to generate three-dimensional shape information, a position of the unmanned flight body 14 is positioned by a positioning part 14D to generate positioning information, and a shape of the water bottom 22 is generated by a water bottom shape information generation part 12F as water bottom shape information shown by coordinate information on the earth on the basis of the three-dimensional shape information and the positioning information. A load member 30 is connected to the three-dimensional shape measurement part 14E during measurement, and connection between the load member 30 and the three-dimensional shape measurement part 14E is released when the measurement is finished.SELECTED DRAWING: Figure 2
【課題】コストを抑制しつつ構成の簡素化を図る上で有利な水底形状測定装置を提供する。【解決手段】無人飛行体14に支持部材20を介して吊り下げた3次元形状測定部14Eを水中に位置させて水底22の3次元形状を測定し3次元形状情報を生成すると共に、測位部14Dにより無人飛行体14の位置を測位し測位情報として生成し、それら3次元形状情報および測位情報に基づいて水底形状情報生成部12Fにより水底22の形状を地球上の座標位置で示される水底形状情報として生成する。測定中の3次元形状測定部14Eには荷重部材30が接続されているが、測定が終了した際には荷重部材30と3次元形状測定部14Eとの接続は解除される。【選択図】図2
